qimage2ndarray 1.4

qimage2ndarray is a small python extension for quickly convertingbetween QImages and numpy.ndarrays (in both directions). These arevery common tasks when programming e.g. scientific visualizations inPython using PyQt4 as the GUI library.

* Supports conversion of scalar and RGB data, with arbitrary dtypes and memory layout, with and without alpha channels, into QImages (e.g. for display or saving using Qt).

* qimage2ndarray makes it possible to create ndarrays_ that are *views* into a given QImage_'s memory.

This allows for very efficient data handling and makes it possible to modify Qt image data in-place (e.g. for brightness/gamma or alpha mask modifications).

* `Masked arrays`_ are also supported and are converted into QImages with transparent pixels.
